SPECIFICATION forming roart of Letters Patent No. 311,696, dated February 3, 1885.

Application filed June 23, 188-1.

To all whom, it may concern:

Be it known that I, JOHN A. WALsI-i, a citizen of the United States, residing at Ware ham, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Closed Boxes for Containing Iron, Steel, 850., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

forming part of this specification, in which Figure l is a perspective view of the bottom of my improved box. Fig. 2 is a like view of the side pieces. Fig. 3 is a perspective View of the bottom with the side pieces placed thereon. Fig. 4 is a plan View of the box complete without a cover. Fig. 5 is a side elevation of the same with the cover in place. Figs. 6 and 7 are modifications to be referred to. My invention relates to certain improvements in the manufacture of closed boxes for containing iron and steel to be welded in rolls or squeezers, or under the hammer, or by any other well-known process; and my invention consists in the peculiar arrangement, construction, and combination of devices, to be hereinafter more fully set forth, and specifically pointed out in the claims.

The object of my invention is to provide a 0 cheap and rapid means for manufacturing boxes by which scrap iron and steel will be practically protected from the air during the process of welding.

In heating scrap-iron all exposed surfaces are oxidized, and a loose pile of this material, admitting air throughout its interior, exposes a much larger area of surface to be'oxidized than the same weight of iron will do if inclosed in an iron box, because in the latter 40 case the exterior surface only is oxidized; hence there is great economy in healing the material in closed boxes, which can be constructed without the expenditure of much time or money, and also as scrap-steel cannot be welded upon a large scale except by excluding the air. If heated in the open air, the steel will melt or burn before it reaches a welding heat. To remove these difficulties is the purpose of my invention.

The material used in constructing my boxes is common muck-bars, so called, being (No model.)

puddled iron rolled from the'puddled ball directly into bars. Scrap-bars or other more costly materials may be used for special purposes; but for ordinary work I prefer to use the material above referred to; and in making the boxes I also prefer to use the widths of muck bars commonly rolled in all muckmills-that is to say, bars three inches, four inches, and six inches wide. Other widths may be used when the dimensions of the desired pile require it.

In order to more fully describe my invention, I will now describe one of my boxes to be used as hereinbefore stated, the material placed therein to be rolled into nail-plate in a mill with grooved breaker-rolls, the grooves about twelve and one-half inches wide.

The bottom of the box is made of two pieces of muck-bar, each thirteen inches long, six inches wide, and of any desired thickness. These bars, which I have designated in the drawings by the letters A and B, are shown in Fig. 1 lying side by side, so as to form a substantial bottom, while the top or cover L, Fig. 5, is constructed precisely in the same manner. The four sides are made from two pieces, 0 and D, of muck-bar four inches wide, each cut to a suitable length, and each formed with two bends, so as to obtain substantially a l shaped form, and by this construction each piece contains one full side and a part of each of two other sides, as shown in Figs. 2 and 3. Thebending of these side pieces maybe done by any simple machinery.

In putting the box together the bottom pieces, A and B, are laid upon a piling-bench, and the side pieces, 0 and D, placed upon them in the manner shown in Fig. 3, and the ends 6 e ff of the bent portions being placed in close contact with each other; and in order to make a good weld the pieces F F, (see Fig. 4,) which are also made of muck-bars about four inches wide, may, if desired, be used, being placed in such manner that they overlap the ends of the side pieces, 0 and D. Then the box is complete, with the exception of the cover before referred to. 1

I do not wish to limit myself to the exact form of the side pieces, 0 and D, as shown in ice Figs. 2, 3, and 4, in which the bent portions are shown as being of the same length, because,

as shownin Fig. 6, these bentportions are made of unequal. lengths; and, again, in Fig. 7 we show it is not necessary that the main portion of the side pieces and the bent portions should be of the same length, as in this figure (7) the portions G are somewhat longer than the portion D, and the bent portions H of the side piece 0 are comparatively short and pass between the ends of pieces G. In this case the welding piecesF may be dispensed with, ifdesired.

In using boxes of the description herein set forth, the side pieces, 0 and D, having been placed upon the bottom A and B,.the space inclosed by the side pieces is filled with scrap iron or steel, or both, and the cover L placed in position. This cover may be large enough to slightly overlap the side pieces and completes a good substantial box without the aid of other fastenings; and, if desired, the iron bottom A B may be replaced with a wooden one, as is customary in heating open scrap-piles, and

the iron sides will come in closer contact with the bottom of the furnace as the wooden bottom burns away, and the entrance of air will thus be prevented.

' I am aware that boxes with three sides have been made of a single bent bar for the puras described, the welding pieces F F, by means pose of containing scrap to be welded; but they simply hold the material together in con- 0 Venient form for welding without regard to the exclusion of air, and they are left open for the free admission of air. This I do not claim as my invention, as the principal feature of my box is the exclusion of the air; but 35 What I do claim, and desire to secure by Letters Patent, is

l. A device for containing iron or steel scrap, the same consisting of a bottom divided into two or more'parts, A and B, the l shaped side pieces, 0 and D, and acover, L, substantiall y as and for the purpose herein described.

2. The combination, with the bottom and cover, each consisting of two or more independent pieces, A and B, of the l-shaped side pieces, Oand D, constructed and arranged to operate substantially as described.

3. In a box for containing scrap iron or steel, and in combination with the top and bottom,

O of which the side pieces, and D, arejoined 5 together, substantially as herein set forth.
